VALVE.

SPECIFICATION forming part of Letters Patent No. 237,794, dated February 15, 1881.

Application led July 13, 1880. (No model.)

To all whom 'it may concern Be it known that I, MAHLON M. ZELLEEs, of Kent, in the county of Portage and State of Ohio, have invented certain new and useful Improvements in Valves; and I do' hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled Yin the art to which it pertains to make and use it, reference being had 1o to the accompanying-drawings, which form part of this specification.

In the drawings,'Figure 1 represents in longitudinal verticalsection a valve constructed according to my invention. Fig. 2 is a detached plan View of the valve-stem shown in Fig. l. Fig. 3 is a detached plan view of the guide-nut B. Fig. 4 is a view in side elevation of the same. Fig. 5 is a view in side elevation of the part C of the device shown in zo Fig. 1. Fig. 6 is a plan view of the same. Fig. 7 is a view in side elevation of the valve proper with'its screw and square shank. Fig.

8 is a view of the packing-spring g. Fig. 9 is a view in side elevation of the ring F, which affords a rest to the spring g,- and Fig. l() is a plan view of said ring.

In the said drawings, A is a valve-chamber with its valve-seat a and valve-proper, a.

B is a guide, constructed in the shape of a 3o nut, with male and female screw threads., as shown Vin the drawings, Figs. 1 and 4, and is provided with an opening, b. to prevent the rotation within it of the sha-nk E of the valve, which shankis formed substantially in counter- 3 5 part of the opening b, through which it moves.

C is a shell for containing the valve-stems D and E, packing-spring g, and ring F. It has an inner surface formed in counterpart of the beveled portion d of t-he valve-stem D, and

4o the spring g, exerting a pushing-pressure, op-

erates at all times to insure a tight joint at d.

D is the upper or boss section of the valvestem, and it extends outside of the chamber G to admit of the attachment of a suitable handle for manipulating the valve. The upper valve-stem section has the outer side of its lower portion cut away, and in the upper part of the annular recess thus formed between the cut-away portion and the casing the spiral 5o spring g is fitted. In the lower part of said recess the independent ring F is iitted, and this ring provides hearing for the spring as the latter forces the valve-stem section upward or outward.

It will be seen that the stem D has only a rotating motion within the chamber O, and is not permitted or designed to have any vertical or longitudinal movement.

The packing-spring g, as already intimated, pushing up upon the stem D, operates, in con- 6o junction withthe joint d, as an effectual packmg.

I am aware that Jfaucets have been constructed with a valve and valve-stem made in a single piece, the valve-stem being provided with a collar to close the opening at the upper end of the casing, a spiral spring being arranged to encircle the valve stem and retain the collar in close contact with the valve-casing. Said spiral spring rests upon a packing- 7o ring the edge of which engages with the reciprocating valve-stem. This construction of valve would be impracticable in the type of valve to which my improvelnentbelongs, as an opening must necessarily be formed between the two sections of the valve-stem.I so that it would be practically impossible to employ a packing-ring ittin g the reciprocating portion of the valve.

I am also aware that valves have been con- 8o structed with atwo-part stem, one portion being provided with a screw-threaded socket, in which is received the screw-threaded end of the other portion of the valve-stem, the latter bein g provided with a spline to prevent the rotation of 8 5 the valve. In this construction of valve no packingis provided for preventing the escape of water through the joint of the valve-casing or past the non reciprocating portion of the valvestem. Hence I would have it under- 9o stood that I make no claim to the construction of valve above referred to, but restrict myself to the particular construction and arrangement of parts shown and described.

In my improved construction ot' valve the 95 upper portion of the valve-stem is reduced in size near its lower end, thereby forming an annular chamber between the valve-stem and casing, in which chamber is placed a spiral spring, the upper end of which rests against zoo a shoulder on the Valve-stem aud retains its conical shoulder in snug` eoutaet with the valveeasing. The lower end ot' the spiral spring` rests upon a cylindrical packing-ring` and retains the lower edge thereof in elose Contact with the Valve-easing', thereby preventing` any escape of water through the joint ofthe valveeasing, while the cylindrical portion ot' the packing-ring' lits snugly between the valveoasing' and valve-stein, thereby insuring an extended packing` which prevents the escape ot' water past the valve-stem and through the upper portion ofthe valve-easing.

My improved construction ot' valve is simple, effective, and durable.

What I claim is- The combination, with the Valve-easing, and lguide-nut B, screwed therein, said guidenut having an angular opening. b, formed therein,

ot' the valve provided with au angular valvestem, E, whieh ts in the guide-nut B, the shell C screwed into the guidediut, the Valveoperating` stem screw-threaded to receive the screw-threaded end ot' the valve-stem, anda ring', l, and springr g, interposed between the valve operatingr stem and valve easing, said ring being seated upon the upper portion of the guide-nut, and the spring bearing against an annular shoulder formed on the valve-0perating' stem, substantially as set forth.

In testimony whereofl have signed my name to this speeilieation in the presence of two subscribing witnesses.
